Issue with unloading Tapes into use slots in silo

OK - I would try the following:

Empty the library - making sure no tapes are in drives

Update the inventory making sure all tapes have dissapeared from the library section of the admin console

If any remain the right click then and select "Move" and then select StandAlone so that nothing shows as being in the library in NetBackup

Next re-run the device configuration wizard against the library

Then re-inventory the library and try again to see if this puts things right

If it still goes wrong call Quantum and maybe get the latest fireware the the tape library

Also makes sure you do not have any drivers loaded for the robot in Windows (assuming you are using Windows Media Servers - if you do ten roll them back so the library shows in device manager as an "unknown medium changer" (if you do this you will need to re-boot and re-run the device configuration wizard)

Hope this helps
